Why are you measuring hashes/s in FLOPS?
I assume it's because
bitcoinwatch shows TeraFLOP/s (as well as Gigahashs/s).
What does that even mean? There is no floating point in hashing.
It means exactly what I said: that bitcoinwatch displays TeraFLOP/s as well as Gigahashs/s. I have no idea why; you'd need to ask them.
